I already played my opponent from yesterday evening a year or so ago. At that time, he accepted the f3 pawn and was swept away by a berserk attack. Have you ever seen the series "Vikings" ? Well, I looked like Ragnar Lothbrok and England was there to conquer.
Yesterday evening, my opponent choose the more cautious path - he initially declined the offered pawn but could not resist lateron.

Vikings have set ashore and immediately set camp.
King Aelle of Northumberland believes he won the first battle, but Ragnar sees it differently.
7...Bd6 8.Nf3 Nc6 9.Bd3 e5 ?
It is strange what the sight of a berserk viking does to man. King Aelle should have tried to reduce the viking forces by 9...Nb4, and if this fails, set up an outpost with Nd5.

Now Ragnar makes a premature attack, but king Aelle doesnt really benefit from this mistake.

The remainder of the game is of no interest to us - we dont want to witness the massacre that Ragnar imposes on the poor English defenders. But the suggested Viking attack certainly has some potency in it - especially as the defender is likely to make mistakes when faces with this unusual attack.
Editors note : This story is historically correct - vikings got into contact with chess when they travelled the seven seas, Ragnar did invade England, king Aelle suffered a terrible blow, and yes, the vikings would have played the Blackmar-Diemer if it had already been invented...
